Beta is "1/2-inch" (Both consumer and pro versions).
3/4-inch is "U-Matic" (Sony's name, there will similar "U-names"
by other manufacturers.)
DV is "better" than all those formats, at least according to the
rank-list at http://www.adamwilt.com/DV-FAQ-tech.html
That means, at least to my way of reasoning, that 5:1 compressed
DV is a suitable archival format for Beta, 3/4U, and videodisc.
"Suitable" meaning that it is of sufficiently higher quality so that
you will see no significant further loss in the quality of the video.

I would be very surprised if AVI-DV were not easily decoded (and
viewed/converted) in 5-10 years. Remember that once it is in digital
form, there are no further "generation losses" from copying.
